Maria and Joanna and katricia's 840 In the ratio of the age Maria and Joanna At 20 years each Katricia is 30 years Calculate the share for each of them

To calculate the ratio of their ages at a 20:20:30 ratio, we need to divide the ages by the total sum:

Maria: 20 / 70 = 2/7
Joanna: 20 / 70 = 2/7
Katricia: 30 / 70 = 3/7

To determine their share, we simply multiply each individual's share by the total amount:

Maria: 840 x 2/7 = 240
Joanna: 840 x 2/7 = 240
Katricia: 840 x 3/7 = 360

So, Maria and Joanna will each receive $240, and Katricia will receive $360.
